Abstract
This study was conducted to determine the suitable light intensity for the development of white-leg shrimp in intensive bioflocs system. The experiment included five treatments with different light intensities such as (i) natural light condition, (ii) dark condition, (iii) compact light 30w, (iv) compact light 55w and (v) compact light 110w. Shrimps were cultured in bioflocs system (C: N = 15: 1) with 300L of culture volume, 15‰ of salinity and 150 shrimp/m3 of stocking density. The initial shrimp weight and length were 0.54 g and 3.69 cm, respectively. After 90 days of culture, the results showed that water parameters were in suitable ranges for normal development of shrimp. The length of shrimp fluctuated from 11.9 – 12.9 cm and weight was 18 – 21.9 g. Besides, the highest shrimp weight (21.9 g) was found in control treatment but there was no significant difference compared to treatment used compact light 55W (20.5 g). Control and compact light 55w treatments presented the lowest FCR but no significant difference was found among all treatments. Using compact light 55w showed the highest survival rate but there was no significant difference among treatments. Therefore, compact light 55w could be applied to indoor-bioflocs systems which will not impact on shrimp growth and survival rate.
